1661 code means your ICP sensor is toast, my man. If you've been crawling around in your engine bay recently you could have crunched it (it's on your drivers side head, to the front of the fuel bowl), or it may have crapped out on it's own.

Ok I think I have It figured out. I opened the hood jiggled the wires that go to the pcm and it started right up. I forgot but I did that once before and it started . There is a bolt that holds a plastic cover over the PCM that is loose. Anyone know if the bolt holds the connection together or is it just for the cover?
Thanks people. I did replace the IPR a while back and I thought that fixed the problem till today. The IPR was big dollars too. Maybe Ill pull the conection and clean things up befor I tighten that loose bolt.
